Bruce Lee's third time leading a feature and far better than the first two, probably because he also wrote and directed. Famous for its climatic fight with Chuck Norris in the Colosseum in Rome.
As always the plot doesn't make a tonne of sense. Bruce gets sent by Nora Miao's uncle to help her out in Rome where the restaurant she just inherited is under pressure from the local hoods (mafia). She wanted a lawyer but for flimsy reasons everything is settled with martial arts and so Bruce is her man. He once again disappoints her in the love business. There seems to be a rule that you only get one go per murder method (why not try again with guns?) and that the Chinese form(s) dominate Karate. Secretary Ping-Ou Wei is very camp, very weird.
Roger Ebert: two stars. The version I saw apparently cut all the translation crap that stuck in his craw. #58 on the Golden Horse list of the 100 Greatest Chinese-Language Films. Excess details at Wikipedia.
